Hello everyone!

The storm that we have been dealing with yesterday is on its way out with just a few wraparound snow showers. Any falling snow will end by around 7 this morning with the Midcoast hanging on to the flakes the longest. However, even as skies clear and the snow moves out, we must still contend with its impacts.

As it intensifies, it will pull in a large volume of cold air in behind it which will do a few things. First off, it will make it very, very cold. Combined with the winds needed to transport all this cold in, today will feel absolurely frigid. As a result of low temps and powerful winds, gusting over 30mph at times, the NWS has issued a wind chill advisory for the mountains so bundle up if you must go outside. The second, and maybe the more important lasting impact will be to set the stage for our next storm, moving in Sunday night.  By the time snow gets ready to arrive, temps will be below 0 for many areas with temps going down to 10 below in the mountains.

With such deep dry, cold air in place, when the moisture arrives, the snow ratio goes into the clouds. Snow ratios across MA, CT, and RI will be in the 12-15:1 range meaning for every 1″ of liquid, 12 to 15″ of snow falls. Up here in Maine, we’re looking at ratios of 20-25:1. Needless to say, that is very fluffy snow, so even though we probably won’t get a lot of liquid, snow totals could be decently high just from the ‘fluff factor’.

I’ll have another update with more maps this evening.
